Circuits are protected from timing attacks by adding a random delay to mask any relation between contents of processed information packages and the processing time required between in- and output signals of protected circuits. This random delay has to be performed preferably inside the protected volume and can be realized by one or more random delay buffers that are realized by means of e.g. random shift-registers. Further protection may be provided by situating the circuits in a single chip housing, such that the signals thereof interfere with each other and it is difficult to obtain information therefrom. A physical barrier may be provided in order to prevent or at least limit physical access to for example at least one TPM chip arranged inside of the barrier. The physical barrier comprises an impedance, i.e. in form of a capacitor with capacity C and or resistor R and or inductivity L, for example formed by two of the reflector layers of the barrier with an absorbing material in between. Any impedance (i.e. capacity C and/or resistance R and/or inductivity L) change can be detected and any impedance (i.e. capacity and/or resistance and/or inductivity L) change beyond a chosen threshold is indicative of an attempt to physically destruct or enter the barrier. Upon detecting an impedance (i.e. capacity C and/or resistance R and/or inductivity L) change beyond the threshold, any suitable action may be performed, such as deleting all information from the chip, destroying the chip or providing wrong information. The barrier may also act as a reflector for reflecting the desired signal of the at least one chip, such that the desired signal and the reflected signals interfere with each other and it is difficult to obtain information therefrom.
